Un estudio para averiguar si el enfortumab vedotín administrado con pembrolizumab ayuda a las personas con cáncer de vejiga músculo-invasivo a conservar su vejiga

30 de octubre de 2026 actualizado por: Astellas Pharma Global Development, Inc.

Un estudio abierto, de un solo brazo, de fase 2 para evaluar Enfortumab Vedotin más Pembrolizumab para la preservación de la vejiga en participantes con cáncer de vejiga músculo-invasivo (EV-209)

People with a type of bladder cancer called muscle-invasive bladder cancer have cancer that has spread into the muscle wall of the bladder. The standard treatment is to have chemotherapy, followed by surgery to completely remove the bladder. This has a significant impact on people with long-term life-altering changes. There are also limited options for people who cannot have chemotherapy or who do not want their bladder removed.

Studies show that enfortumab vedotin, when given with pembrolizumab, can help people with advanced bladder cancer. This treatment has also worked well for people with muscle-invasive bladder cancer who can't receive chemotherapy when it was given before and after bladder-removal surgery. However, some people can't have or won't have this surgery. There is still a need for new treatments that let people keep their bladder. This is especially important for people who respond well to the enfortumab vedotin, when given with pembrolizumab, and may benefit from continuing this study treatment instead of having surgery.

The main aims of this study are to check how many people continue to respond well to enfortumab vedotin with pembrolizumab and how many people have their bladder intact after 2 years.

People in this study will be adults who have muscle-invasive bladder cancer and are able to have surgery to remove the bladder.

People cannot take part if they have nerve damage (sensory or motor neuropathy), have had certain other cancers, have diabetes that is not under control, or have had a transplant.

People will receive infusions of enfortumab vedotin on the 1st and 8th day of 3-week (21-day) cycles. They will also receive pembrolizumab on the 1st day of every 3-week cycle. There will be safety checks at each visit with checks of the tumors at some visits. The doctors will continue to check for medical problems throughout the study.

People will continue to receive study treatment unless their cancer doesn't improve after 9 cycles of study treatment, or until their cancer gets worse, they can't tolerate the study treatment, they start other cancer treatment, they or the doctor decides the person should stop receiving study treatment, or sadly they pass away.

People's whose cancer gets worse or doesn't improve after 9 cycles may need bladder surgery, radiotherapy or chemotherapy. People will visit the clinic after they stop their study treatment, in which they will be asked about any medical problems and have a health check. After this, people will continue to have scans every 12 weeks (3 months) for the first 2 years until their cancer gets worse. After this, if their cancer doesn't get worse, they will continue to have scans every 24 weeks (6 months) for up to 5 years to check for any changes in their cancer. After people's cancer gets worse, they won't have any more scans but will have telephone health checks every 3 months.

  • Participant has ≥ N2 disease or metastatic disease (M1) as identified by imaging

  • Participant has a history of uncontrolled diabetes mellitus within 3 months prior to screening. Uncontrolled diabetes (within 3 months before first dose) is defined as hemoglobin A1c (HbA1c) ≥ 8% or HbA1c between 7% and < 8% with associated diabetes symptoms (polyuria or polydipsia) that are not otherwise explained. The lowest HbA1c during the screening period will be used to determine eligibility.

  • Participant has a second malignancy diagnosed within 3 years before first dose of study intervention, or any evidence of residual disease from a previously diagnosed malignancy. Participant with non-melanoma skin cancer, localized prostate cancer treated with curative intent with no evidence of progression, low-risk or very low-risk (per standard guidelines) localized prostate cancer under active surveillance/watchful waiting without intent to treat, or carcinoma in situ of any type (if complete resection was performed) are allowed.

  • Participant has known active keratitis or corneal ulcerations. Participant with superficial punctate keratitis is allowed if the disorder is being adequately treated.

  • Participant has a history of (non-infectious) pneumonitis/interstitial lung disease (ILD) that required steroids or has current pneumonitis/ILD.

  • Participant has a history of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis on screening chest computed tomography (CT) scan.

  • Participant has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior the first dose of study intervention. Inhaled or topical steroids are permitted in the absence of active autoimmune disease. Physiologic replacement doses of corticosteroids are permitted for participants with adrenal insufficiency.

  • Participant has active autoimmune disease that has required systemic treatment in past 2 years (i.e., with use of disease modifying agents, corticosteroids or immunosuppressive drugs).

    • Replacement therapy (e.g., thyroxine, insulin, physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed.
    • Brief (< 7 days) use of systemic corticosteroids is allowed when use is considered standard of care.
    • Participant with vitiligo, psoriasis, type 1 diabetes mellitus, hypothyroidism, or resolved childhood asthma/atopy will not be excluded.
    • Participant requiring intermittent use of bronchodilators, inhaled steroids, or local steroid injections will not be excluded.
    • Participant with hypothyroidism that is stable with hormone replacement therapy or Sjögren's syndrome will not be excluded.
  • Participant has received prior therapy with an anti-programmed cell death protein 1 (PD-1), anti-programmed death-ligand 1 (PD-L1), or anti-programmed death-ligand 2 agent or with an agent directed to another stimulatory or coinhibitory T-cell receptor (e.g., CTLA-4, OX-40, CD137).

  • Participant has received prior systemic anti-cancer therapy for MIBC/non-muscle invasive bladder cancer (NMIBC), or received prior systemic anti-cancer therapy including investigational agents (including enfortumab vedotin or other monomethyl auristatin E-based antibody-drug conjugates) within 3 years prior to screening.

NOTE: Prior treatment for NMIBC with intravesical instillation therapy such as Bacillus Calmette-Guérin or intravesical chemotherapy is permitted. Prior systemic treatment (including, but not limited to, anti-PD-1/PD-L1 treatment with pembrolizumab, etc.) received for NMIBC is not permitted.

  • Participant has received a partial cystectomy of the bladder to remove any NMIBC or MIBC.
  • Participant has received any prior radiotherapy to the bladder.
